What is it?

Green Tea Extract, derived from the leaves of the Camellia Sinensis plant, is one of the most popular and well-researched Vietnam Plant Extracts available today. At Nacipe’s plant extract factory, we source and process high-quality green tea leaves from Vietnam, ensuring purity and high concentrations of active compounds. Unlike fermented teas, green tea is minimally processed, which helps preserve powerful antioxidants like catechins and EGCG —the key contributors to its wide range of health benefits.

Potential Uses and Benefits

Green Tea Extract has been widely used in both traditional and modern health practices for its diverse benefits. At Nacipe’s Vietnam plant extract factory, we offer Camellia sinensis extracts tailored for use in supplements, functional beverages, and beauty products. Documented benefits include:

• Weight management – May help boost metabolism and promote fat oxidation.

• Heart health – Linked to improved cholesterol balance and reduced blood pressure.

• Cognitive function – Supports focus and mental clarity thanks to L-theanine and caffeine.

• Skin health – Antioxidants in Green Tea Extract help combat skin aging and inflammation.

• Immune support – Catechins in green tea may enhance immune defenses and reduce oxidative stress.

These advantages make Green Tea Extract a leading ingredient in wellness-focused formulations worldwide.

Catechins and EGCG: Green Tea’s Key Actives

The benefits of Camellia Sinensis stem largely from its rich supply of catechins, a class of polyphenols known for their antioxidant properties. Among them, EGCG is the most potent and extensively studied. EGCG plays a central role in many of green tea's health benefits—from supporting cardiovascular wellness to aiding fat metabolism and cellular protection. At our plant extract factory, we standardize our Vietnam Plant Extracts to ensure high EGCG content, offering consistent quality for nutraceutical and cosmetic applications.

Clinical Summary

Green Tea Extract is backed by studies showing benefits for heart, brain, and metabolic health.

Research suggests that Green Tea Extract may lower risks of dementia, high blood pressure, and cardiovascular disease. Its role in cancer prevention shows mixed results—some evidence points to protective effects against liver, oral, and colorectal cancers, while other findings remain inconclusive.

Green Tea Extract also shows promise in lowering cholesterol, improving blood sugar in type 2 diabetes, and supporting weight loss, particularly in overweight adults and women with PCOS. Early studies suggest benefits for skin, muscle preservation in seniors, and managing side effects of cancer treatments, but further research is needed.

Moderate intake is considered safe. Clinical data support EGCG doses up to 400 mg/day. Higher intakes, especially on an empty stomach, may raise liver enzyme levels. For best results, Green Tea Extract should be used responsibly and under professional guidance.

Potential Side Effects

Green Tea Extract is generally safe for most users when consumed in appropriate amounts. Potential side effects may include:

• Mild digestive discomfort or nausea

• Headache or dizziness (particularly in high doses)

• Sleep disturbances due to caffeine content

• In rare cases, liver function issues with excessive intake

Those with liver conditions, caffeine sensitivity, or those who are pregnant should consult a healthcare provider before use.

Mechanism of Action

The health-supporting effects of Green Tea Extract come from the interplay of its active compounds, particularly EGCG, caffeine, and L-theanine. These components work through several pathways:

EGCG may promote heart health by increasing HDL (good) cholesterol, lowering LDL (bad) cholesterol and triglycerides, and supporting healthy blood pressure. It also stimulates nitric oxide (NO) production, helping blood vessels relax and improve circulation.

Research suggests Green Tea Extract enhances brain function by boosting connectivity in regions responsible for memory. EGCG may also reduce tau protein buildup, a marker linked to neurodegenerative diseases.

EGCG and other green tea polyphenols may inhibit enzymes involved in DNA replication and cell growth, potentially slowing the progression of certain cancers. In lab studies, EGCG has shown the ability to suppress colon, leukemia, and skin cancer cell development by interfering with DNA synthesis, reducing inflammation pathways, and regulating pro-growth proteins like VEGF.

Together, these compounds help regulate metabolism, support heart and brain health, and strengthen the body’s response to stress.
